MECHANISM FOR REDUCING OLD RAILS TO RAILS 0F SMALLER SIZE.

SPECIFICATION forming part of Letters Patent No. 366,395, dated July 12,1887.

Application filed April l1, 18e?. Serial No. 234,436.

T0 all whom it may concern.-

Be it known that I, WILLIAM HOPKIN HoWELLs, a citizen of the UnitedStates, residing at Bridgeport, in the county of Belmont and State ofOhio, have invented a certain new and useful Process for Reducing OldRailway- Rails to Small T-Rails; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse the same, reference being had to the accompanying drawings, whichform a part of this specification.

My invention relates to a process for reducing old railway-rails tosmall T-rails, the object being to provide ameans whereby the web of therail may be staved or increased in thickness to correspond in thereducing to the head and base of the same. rIhis I aecomplish by meansof suitably-constructed set of rolls having alternately arranged thereina series of staving and shaping grooves acting in conjunction withguide-boxes having bellmouthed entrances and a flat cap or top toprevent the rails from warping, together with certain details ofconstruction and combination of parts, as will be fully describedhereinalter.

In the accompanying drawings, Figure lis a frontl elevation of myimproved rolls, having the guide-boxes removed therefro1n,\vhich areconstructed in accordance with my invention. Fig. 2 is a sectional sideelevation of one of the guide-boxes. Fig. 3 is an end View of the same,showing the position of the rail y while passing through the same.

To put my invention into practice, I provide a set of rolls, a, havingalternately arranged therein a series of dummy (b) and shaping grooves(c) gradually decreasing in size but of the same form throughout. At thefront of each (No model.)

of these grom'e b and c I place a suitablyconstructed guide-box, el,having a bell-mouthed entrance, @,whieh allows the rails j" to be easilyentered and guided to the proper groove.

In reducing an old and worn rail to a small T-rail, the same is given aproper degree of heat and first passed through a dummy-groove, b, whichoperation staves or increases the thickness of the web, the dat top orcap of the guideboX d preventing the same from Warping. After this passthe rail f is rapidly7 entered into a shaping-groove, c, which reducesthe railf in size. The next pass is through a dummy-groove, I), whichfurther staves the Web of the rail, being somewhat smaller than theprevious dummy-groove. This operation is continued until the rail f hassuccessively passed through all the grooves b and c of the rollse.

By alternately staving the web of the rail and shaping the samesufficient metal is gathered in the web to correspond to that ot' thehead and foot.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, isn l. The improved apparatus for the purposedescribed, consisting of a pair of rolls havingalternatedummystaving-grooves and shapinggrooves decreasing in internalarea from one end to the other, and a guide of rectangular form having abell-mouthed entrance, substantially as speciiied.

2. The combination, Witha pair of rolls for the purpose described, of aguide of rectangular form having a bell -mouthed entrance anda removabletop, substantially as specified.
